Helmer Eron Sheean generates considerable suspense and sustains a sense of mounting dread throughout much of his debut feature, “Errors of the Human Body.” So it’s all the more disappointing when this sci-fi thriller starts to run out of steam somewhere around the three-quarter mark, and slowly sputters toward a confusing, unsatisfying conclusion. Michael Eklund’s subtly drawn performance as a scientist seeking a cure for the rare malady that killed his infant son is undeniably impressive, but it’s doubtful that will be enough for genre fans who’ll be left scratching their heads. Prognosis: fleeting theatrical exposure, minimal homevid shelf life.

After his son dies and his marriage collapses, American geneticist Geoff Burton (Eklund) relocates to Germany to continue his research at a corporate facility. But he starts to distrust his colleagues, an old flame (Karoline Herfurth) and an arrogant rival (Tomas Lemarquis), while working on a regenerative drug that, as Burton learns the hard way after an inadvertent self-dosage, has unfortunate side effects. It’s easy to respect Sheean’s attempt to avoid monstrous transformations and similar sci-fi cliches, but this slickly packaged pic proves to be all buildup and no payoff.
